I'll add in some random musings I'm having with TC ...
Before TC there was ... manual temperature control by the vaper. Yes, before TC there was tc. Nobody wanted to burn their juice and most vapers would avoid it. We learned to do this by matching the build to the atty - it's airflow particularly - the mod, the power setting and the juice. We controlled temperature by inhalation and the duration of the fire period. In this manual way we achieved the vape we wanted, as warm or as cool as we wanted, and we learned to detect the imminent dry hit.
Then came TC technology and we found ourselves constrained initially to just one wire, not because it was safer or better to build with, not for any justifiable reason other than the developers could mathematically predict/estimate the coil temperature from the resistance change of this particular wire. More wires eventually got added. Vapers then had to relearn their wicking and coil building to use this new technology. But for what benefit?
If the answer to this question is safety then it presupposes that vapers are not safe using non-TC vaping methods. That seems to be full of assumption. Vaping practices vary widely, some vapers are pretty conservative whilst others are pushing the envelope beyond reasonable risk boundaries.
Do we know yet whether TC wires - Ni200, Titanium, NiFe30, NiFe48 etc - are safer than kanthal?
We know that TC will prevent us from burning the wick but TC in itself does not prevent the user from burning the juice. You can singe a wick using TC yet many vapers using kanthal do not singe their wicks. How can TC be safer for them?
If safety is going to be the winning argument for TC then it needs evidence to back that up. Without evidence it's simply a matter of faith, isn't it? TC is going to have to do a lot better than show people wicks that aren't burnt.
I understand
@danb 's point about TC being another category of vaping ... afterall we choose our hardware, we prefer one type of juice over another, we prefer one type of wick over another, so vapers can also choose a TC vape over a non-TC vape simply because they prefer the experience. Stating a preference is reason enough for me ... as long as I'm not asked to share their faith.
